php乱码问题
今天遇到了一个很奇怪的乱码问题，自己无意中解决了，但不知道是什么原因，只好记下来，防止以后再出现这样的问题。
当我把php语句写到下面的页面头信息之前的时候，这些php输出语句都输出的是乱码，包括用echo输出的js。如：echo "<script languge=javascript> alert('添加成功!');location.href = 'device_add.php';</script>";弹出来的“添加成功”也变成了乱码。
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<LINK REL=stylesheet HREF="style.css" type="text/css">
<title>.............</title>
如果把php语句放到页面头信息之后，则不会出现乱码了。
